A few of the obligatory April Fools' Day pranks tech firms will roll out today will be funny. Some will be believable. To confirm the jokes, and help you avoid endless "Did you see this" emails, we're rounding them up here.

In the Google-verse

Google goes bananas on April 1. Every big department, and some small, gets their shot at adding a "new service" or "killer feature" to their products. If you see something announced on a Google blog today, unless you're in a time machine and it's about Gmail in 2004, chances are, it's not true. Here are the notable Google pranks:

Google Voice Standard ModeIt's funny because when I call my friends' non-Google-Voice numbers, I really do get prompts for "numeric pages"—which just texts that person the number I just called from.

Google Translate for AnimalsFunny joke, sure—but Google actually released an Android app in the Market that pretends to listen and provide English translations. It's probably right that my Rubenesque cat is asking, "Please, sir, may I have some more?"

Everywhere else

Just because every other company doesn't give their employees one day a week to pursue their pranks and pet projects doesn't mean they can't also get pseudo-serious on April 1.

guest@xkcdXKCD wins the April 1 war, or at least ties for second (see directly below), by giving his already geek-tastic comic site a Unix-like interface for the day. Go ahead — type "ls" to list files, and type other commands (like "man next") for loads of little goofs. Update: Want to see the full list of responses? zTnL points us to the full JavaScript file, in which you can hunt down all the little one-liners and marvel at the code.

RedditAt least as of this morning, everybody is an Admin at the community posting/voting site. No, seriously—everybody is an admin.

More noble attempts to round up the April Fools' shenanigans can be found at Search Engine Land
and, in particular, TechCrunch's 2010 list
, which they plan to update throughout the day. It's quite a scroll already.
We are, most certainly, looking to hear about the pranks you almost thought were real today, or just the worthy jokes you've seen around the tech and corporate world today. Tell us about them in the comments, and we'll add them to this post.
